Google on Monday announced a change to how it offers free cloud storage to its users: 15GB will now be shared across Google Drive, Gmail, and Google+. This change will start rolling out over the next couple of weeks. Previously, Google offered 10GB for Gmail plus another 5GB for Drive and Google+ Photos. Now the company has decided that it makes more sense to unify the free storage across its three services. As part of the change, Google is tweaking its Drive storage page to show a pie chart that breaks down your storage use across the trio. As before, you can still upgrade your storage space. Plans range from $4.99 per month for 100GB to $799.99 per month for 16TB. What is most interesting for Gmail users here is that the 25GB upgrade is no longer the limit. Any additional storage you purchase will also apply to Google’s email service.
